I enclose pictures of a rock that I found in my garden a week ago. I have tried to identify the rock. Having done some research, I am still unclear as to what type of rock it is. At first, I thought it was a slag and now I wonder if it is a meteorite. The rock presents some of the characteristics:

a) It is rather heavy for its size (weighs 86 grams) and is attracted to magnet

b) It has a thin, black coating (fusion crust?)

c) It doesn't leave a streak when scratching the unglazed side of a tile

I know the above does not mean it is a meteorite.

I would be very grateful if someone could help me identify what type of rock it is.
